TextArea generates onTextChanged events when OSK is displayed or screen is rotated

[Ugo Riboni]

In the attached test case the Label at the bottom counts the number of times the TextArea received an onTextChanged event.

Steps to reproduce:
* Tap on the TextArea to start editing: the count increases by one or more while the OSK shows up
* While the OSK is visible, rotate the device: the count increases further

Expected result:
None of the above should happen and the count should never change unless the user types in something with the OSK.

(tested on maguro on build 100)

The same issue happens replacing TextArea with TextEdit

Works for me as expected with a clean flashed galaxy nexus. Flashed via "phablet-flash ubuntu-system --channel trusty"

Just ran the test on an a trusty-based image (r11), and I can confirm the problem.

By the way, I think entering just one character in the field should generate only one textChanged event, but apparently it triggers at least 4 of them, as evidenced by the counter increment.

@olivier: how exactly did you run the example?

cd /tmp
wget https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1243164/+attachment/3887315/+files/test2.qml
adb wait-for-device
adb push test2.qml /tmp

When having the predictive text enabled, this issue doesn't show up anymore:
adb shell sudo -iu phablet gsettings set com.canonical.keyboard.maliit predictive-text true
